Цитата
Followings are general rules of the argument of ACMD41:
(1) If the voltage window field (bit 23-0) in the argument is set to zero, it is called "inquiry CMD41" that
does not start initialization and is use for getting OCR. The inquiry ACMD41 shall ignore the other
field (bit 31-24) in the argument.
(2) If the voltage window field (bit 23-0) in the argument is set to non-zero at the first time, it is called
"first ACMD41" that starts initialization. The other field (bit 31-24) in the argument is effective.
(3) The argument of following ACMD41 shall be the same as that of the first ACMD41.
При нулевом OCR инициализация не должна стартовать.
Нулевой OCR можно использовать для получения правильного OCR.
